Question

The bus admittance (Ybus) matrix of a 3-bus power system is given below.

Considering that there is no shunt inductor connected to any of the buses, which of the following can NOT be true?

Answer

Line charging capacitor of finite value is present in all three lines

Answer

Line charging capacitor of finite value is present in line 2-3 only

Answer

Line charging capacitor of finite value is present in line 2-3 only and shunt capacitor of finite value is present in bus 1 only

Answer

Line charging capacitor of finite value is present in line 2-3 only and shunt capacitor of finite value is present in bus 3 only
